Description

Technical Field

[0001] The utility model relates to the technical field of building wall structures, and particularly relates to an assembled decoration integrated wall for the generator floor of an underground power house. Background Art

[0002] A wall needs to be set in front of the rock wall in the generator floor of the underground power house. In the prior art, the wall of the generator floor of the underground power house adopts a traditional masonry wall, which has the following problems: 1. Long construction period: The construction of the traditional masonry wall requires multiple processes, such as leveling and waterproof mortar, etc., so it takes a long time and may take several weeks or months to complete. 2. High construction cost: The construction of the traditional masonry wall requires a large amount of human and material resources, and the cost is high, which is not conducive to reducing the overall decoration cost. 3. Difficult to guarantee construction quality: There are defects and deficiencies in the construction process of the traditional masonry wall. For example, the waterproof mortar should be on the water-facing side close to the rock wall under normal circumstances. However, due to over-excavation or under-excavation in the excavation of the rock wall, the construction space is insufficient in the under-excavated part, and the waterproof mortar can only be applied to the side of the unit close to the generator floor, resulting in poor waterproof effect. 4. The size of the mechanical and electrical pipeline openings often leads to inaccurate information submission, resulting in the need to adjust the openings in the later stage and a lot of openings need to be re-drilled, which brings great difficulties to the construction and also affects the overall strength.

Pay attention to the treatment of the plate joints during installation.

[0069] The assembled and integrated wall of the present utility model application has the following installation characteristics:

[0070] First, fixedly connect the basic wall 4 with the reinforced concrete water retaining sill 1 and the rock wall crane beam 2 as the main structure of the wall. Then, the outer decorative panel 8 and the inner waterproof layer 7 can be installed synchronously, which can improve the assembly efficiency of the assembled wall.

[0071] During the assembly of the basic wall 4, position and distribute the moisture-proof wall according to the design requirements. After the basic wall 4 is spliced, it can form the main structure of the moisture-proof wall. During installation, first fix a plurality of steel plates 12 on the rock wall crane beam 2 by the second expansion bolts 13. Then, weld and fix the connector 14 with the steel plate 12. Then, relatively fixedly install the U-shaped connector 10 on the reinforced concrete water retaining sill 1, and then sequentially install the basic wall 4 in blocks into the spaces corresponding to the upper and lower U-shaped connectors, and then splice the adjacent basic walls 4, which can increase the stability of the basic wall.

From the perspective of the overall building structure, the structure from the inside to the outside has three layers, namely the inner waterproof layer, the moisture-proof wall formed by the base wall, and the outer decorative panel, all of which adopt prefabricated structures and can be completed by assembly at the construction site, with relatively high quality controllability. The outer decorative panel can be customized and produced according to the preferences of the owner and then assembled. There is no wet operation on site, and if it needs to be replaced after many years, it can be directly replaced.

[0074] The utility model provides an assembled decoration integrated wall for the generator floor of an underground power house, which has the advantages of light self-weight, effectively reducing the structural load, being safe, environmentally friendly, having fewer construction processes, and being easy to hoist and construct.

[0075] The specific advantages are as follows:

[0076] (1) By using simple assembly modes such as "keel bracket + precast panel" to replace the complex technological processes of traditional decoration, the decoration work efficiency is greatly improved, the decoration quality is guaranteed, it is green and environmentally friendly, and it can be widely applied to decoration projects such as roof and wall surfaces.

[0077] (2) The assembled decoration integrated wall successfully avoids the difficult-to-control wet operation construction. By directly using the pre-produced components, on-site operations only need anchoring, supporting, splicing, etc., greatly improving the construction accuracy and enhancing the quality.

[0078] (3) It has the advantages of light self-weight, effectively reducing the structural load, being safe, environmentally friendly, having fewer construction processes, and being easy to construct and install, as well as the advantages of simple construction, short cycle, controllable quality, and environmental protection and energy conservation.
